Depending on the financial institution, certificates can offer various term options. Some certificates can be very liquid allowing for frequent deposits and/or withdrawals without penalty. Other certificates may more closely match the typical rules of a [certificate of deposit](/wiki/Certificate_of_deposit "Certificate of deposit"), allowing the investor to select a term length (typically between 3 months to 3 years) and earn a guaranteed interest rate. These certificates are flexible and allow add\-on payments during the term or withdrawals up to a specified amount without a charge. There are also certificate products that feature an interest rate tied to the stock market, namely the [S\&P 500](/wiki/S%26P_500 "S&P 500") index. While each certificate product has its own rules they all have one common factor, security of the investor's principal.


Do some certificates match typical rules of a certificate of deposit?
