Accepted indicators for stock market valuation
There are several camps for stock valuation, and much of it boils down to your investment style.  A growth investor will not consider something with a 50x P/E ratio to be overvalued, but a value investor certainly would. I would recommend looking up the Fama-French n-factor model (it was 3-factor, I believe they have released newer papers which introduce other factors), and reading The Intelligent Investor by Benjamin Graham.  Graham's methodology is practically canon for many investors, and the methodology focuses on value, while outlining quantitative factors for determining if a stock is under or over valued.
"A bit strange but okay.  The way I would think about this is again that you need to determine for what purpose you're computing this, in much the same way you would if you were to build out the model. The IPO valuation is not going to be relevant to the accretion/dilution analysis unless you're trying to determine whether the transaction was net accretive at exit. But that's a weird analysis to do. For longer holding periods like that you're more likely to look at IRR, not EPS. EPS is something investors look at over the short to medium term to get a sense of whether the company is making good acquisition decisions. And to do that short-to-medium term analysis, they look at earnings.   Damodaran would say this is a shitty way of looking at things and that you should probably be looking at some measure of ROIC instead, and I tend to agree, but I don't get paid to think like an investor, I get paid to sell shit to them (if only in indirect fashion). The short answer to your question is that no, you should not incorporate what you are calling liquidation value when determining accretion/dilution, but only because the market typically computes accretion/dilution on a 3-year basis tops. I've never put together a book or seen a press release in my admittedly short time in finance that says ""the transaction is estimated to be X% accretive within 4 years"" - that just seems like an absurd timeline.  Final point is just that from an accounting perspective, a gain on a sale of an asset is not going to get booked in either EBITDA or OCF, so just mechanically there's no way for the IPO value to flow into your accretion/dilution analysis there, even if you are looking at EBITDA/shares. You could figure the gain on sale into some kind of adjusted EBITDA/shares version of EPS, but this is neither something I've ever seen nor something that really makes sense in the context of using EPS as a standardized metric across the market. Typically we take OUT non-recurring shit in EPS, we don't add it in. Adding something like this in would be much more appropriate to measuring the success of an acquisition/investing vehicle like a private equity fund, not a standalone operating company that reports operational earnings in addition to cash flow from investing. And as I suggest above, that's an analysis for which the IRR metric is more ideally situated.  And just a semantic thing - we typically wouldn't call the exit value a ""liquidation value"". That term is usually reserved for dissolution of a corporate entity and selling off its physical or intangible assets in piecemeal fashion (i.e. not accounting for operational synergies across the business). IPO value is actually just going to be a measure of market value of equity." Ok maybe I should have went into further detail but I'm not interested in a single point estimate to compare the different options.  I want to look at the comparable NPVs for the two different options for a range of exit points (sell property / exit lease and sell equity shares). I want to graph the present values of each (y-axis being the PVs and x-axis being the exit date) and look at the 'cross-over' point where one option becomes better than the other (i'm taking into account all of the up front costs of the real estate purchase which will be a bit different in the first years).  i'm also looking to do the same for multiple real estate and equity scenarios, in all likelihood generate a distribution of cross-over points.  this is all theoretical, i'm not really going to take the results to heart. merely an exercise and i'm tangling with the discount rates at the moment. There are the EDHEC-risk indices based on similar hedge fund types but even then an IR would give you performance relative to the competition, which is not useful for most hf's as investors don't say I want to buy a global macro fund, vs a stat arb fund, investors say I want to pay a guy to give me more money!  Most investors don't care how the OTHER funds did or where the market went, they want that NAV to go always up , which is why a modified sharpe is probably better. Another one I have seen mentioned used is Equity Feed. It had varies levels of the software depending on the markets you want and can provide level 2 quotes if select that option. http://stockcharts.com/ is also a great tool I see mentioned with lots of free stuff. James Roth provides a partial solution good for stock picking but let's speed up process a bit, already calculated historical standard deviations: Ibbotson, very good collection of research papers here, examples below Books It's either a broad benchmark sp500, msci world, lehman agg, and or a cash index. Most will not use a specific benchmark.  While the broad benchmark may not be applicable from my experience its usually there as a proxy for the overall market. That is called a 'volume chart'. There are many interactive charts available for the purpose. Here is clear example.  (just for demonstration but this is for India only) 1) Yahoo Finance 2) Google Finance 3) And many more Usually, the stock volume density is presented together (below it) with normal price vs time chart. Note: There is a friendly site about topics like this. Quant.stackexchange.com. Think of checking it out. William %R is a momentum indicator used for measuring overbought and oversold levels, it is not used to predict the price of a stock. In fact, William %R, like all momentum indicators, is a lagging indicator - meaning the indicator level changes as the price of the stock changes. It ranges from 0 to -100. Usually when a reading is less than -80 the stock can be considered to be oversold, and when the reading is above -20 the stock can be considered overbought. When viewed together with the price chart, this can help provide a trader with entry and exit points into and out of a trade. Your observation is mostly right, that 1 is a the number around which this varies.  You are actually referencing PEG, P/E to Growth ratio, which is a common benchmark to use to evaluate a stock. The article I link to provides more discussion. Edit3: Regarding the usefulness of the bare number itself, it is not useful unless, for example, an employer uses that average in the computation of how many options the employer grants to the employee as part of the compensation paid. One of my employers used just such an average. What is far more common is to use two or more moving averages, of different periods, plotted on a chart.  My original response continues below... Assuming there are 252 trading days a year, the following chart does what you have done but with a moving average: AAPL on Stockcharts.com  Edit: BTW, I looked up the number of Federal holidays, there are 9. The average year has 365.2422 days. 365.2422 × 5/7 = 260.8873. Subtract 9 and you get 251.8873 trading days in the average year. So 252 is a better number for the SMA than 250 if you want to average a year.  Edit2: Here is the same chart with more than one average included: AAPL chart w/indicators Stock valuation is a really sticky business, although they are ways to value it, it is somewhat subjective(expectations are calculated). But it will be at premium most likely, can't tell how much without any numbers.(wouldn't be able to tell with the numbers as well since i do not have any knowledge in the sector) "You cannot determine this solely by the ticker length. However, there are some conventions that may help steer you there. Nasdaq has 2-4 base letters BATS has 4 base letters NYSE equity securities have 1-4 base letters. NYSE Mkt (formerly Amex) have 1-4 base letters. NYSE Arca has 4 base letters OTC has 4 base letters. Security types other than equities may have additional letters added, and each exchange (and data vendors) have different conventions for how this is handled. So if you see ""T"" for a US-listed security it would be only be either NASDAQ, NYSE or NYSE Mkt. If you see ""ANET"" then you cannot tell which exchange it is listed on.  (In this case, ANET Arista Networks is actually a NYSE stock). For some non-equity security types, such as hybrids, and debt instruments, some exchanges add ""P"" to the end for ""preferreds"" (Nasdaq and OTC) and NYSE/NYSE Mkt have a variety of methods (including not adding anything) to the ticker.  Examples include NYSE:TFG, NYSEMkt:IPB, Nasdaaq: AGNCP, Nasdaq:OXLCN.  It all becomes rather confusing given the changes in conventions over the years. Essentially, you require data that provides you with ticker, listing location and security type. The exchanges allocate security tickers in conjunction with the SEC so there are no overlaps.  eg. The same ticker cannot represent two different securities. However, tickers can be re-used.  For example, the ticker AB has been used by the following companies:" Been in tech research for quite some time through both '01 and '08, so I've seen different valuation metrics used at different times of the cycle.  I agree 4Q forward is the norm but I do 6Q forward model and depending on verticals, P/E, P/S or EV/EBIDTA.  And maybe DCF for sanity check.     Usually SSS/MAU/subs are used w/ ARPU or turns/B:B to derive top line. Earnings is an easy number to pull from bbg but the descriptive quality of earnings is not as good as EBITDA or FCF especially some companies choose to talk about adjusted numbers only.     Different strokes for different folks.  I must admit that based on my valuation model both AMZN/NFLX are both hard pass due to their valuation. But I was in AMZN in PA from my quant model.  Different strokes for different folks. Relative valuation is always my go to. Reason being i can make any company a buy or sell by changing assumptions such as growth rate, discount rate ect with a DCF. Still a great exercise to complete on all investments. Also an RV will help you pick the best out of the group (hopefully) rather than take  a stance on whether you can actually predict the future inputs ( no one can) I think others have made the key points. Let me just add: As others have pointed out, the traditional IRA is better if your tax rate in retirement is lower than it is when you are building the account. The Roth IRA is better if your tax rate in retirement is higher. For most people, your income in retirement will be lower than your income in most of your working years. On top of that, a significant percentage of your income will come from Social Security, which is generally not taxed, and so the tax rate you pay on the remaining income will be lower still. If you're just starting out, if you're in your 20s, it's likely that your income will go up significantly in the next couple of decades and so you might be making more in retirement that you are now, and so the Roth is probably your better bet. But if you're in your 40s or 50s you are probably making your peak income, you will have much less in retirement, and the traditional IRA is likely better. If your income is well above average and you are saving enough to have a retirement income well above average, then social security may be a very small part of your retirement and my comments on that may not be relevant to you. It's true that tax rates could change in the future. But will they go up or down? It's also possible that the laws about retirement accounts will change. If you think you have some insight into what will happen in the future you may want to take that into account when making plans. But politics is very hard to predict.
