In a previous article I talked about how important it is to stretch the psoas muscle. This can cause many complications including back pain. To recap, most people have tight and shortened psoas muscles. The common activity of sitting causes our psoas to be consistantly shortened for extended periods of time.
The sale on March 31 is a wash sale. The wash sale period for any sale at a loss consists of 61 days: the day of the sale, the 30 days before the sale and the 30 days after the sale. (These are calendar days, not trading days.
There are perfect end runs around the wash-sale rule, most of which use options strategies. If you sell a stock for a loss and within 31 days buy a call option on that stock, you have violated the wash-sale rule. The penalty of the rule is that the loss on the stock is not crystallized. Instead, the amount of the loss is added to the cost basis of the replacement property; in this case it is the call option.
