Summary:  After declining more than 25% to start the year, the markets have rallied more than 30% to break even for the year. Is this the time to buy?

The market has been bipolar to start the year.  In almost straight lines, the market first declined over 25% and then shot up over 33% to break even for the year.  Given this rapid increase in equity prices over the last two months, you should be cautious to invest new money in the market.  Some stocks are up hundreds of percent over this time frame, and to buy stocks now, is to buy stocks at a relatively expensive price.  The worst time to buy is after a long-rally.  To buy now is to put suckers money into the market.  Wait for a pull back and always buy stocks are your price, but never chase stocks solely because they are going up.  It is a time-tested strategy for losing money.  

Moreover, many experts believe the US economy still faces many challenges to recovery, and investors are being overly optimistic.  Don't buy now because you think you've missed the opportunity to get into the market.  There will be at least one more correction over the next few months that will give you the opportunity to buy stocks at better prices.  

Furthermore, if you happened to buy stocks near the March lows, don't be greedy.  Many investors are sitting on large gains.  For example, one stock I owned, Leucadia (LUK) is up nearly 100% since I bought it.  Even if I believe Leucadia is still undervalued, it is bad technique and unwise not to sell any of my holdings.  DON'T BE GREEDY! Leucadia is only an example. Any stock mentioned, may be sold at any time without disclosure. Please do your own research before buying anything mentioned to make sure it is suitable for your own portfolio.
