Twitter's IPO was at the beginning of Nov 2013 and the stock opened at a price of about $42. By the end of the year 2013, the stock was trading at $69 a share. So, if you had $100,000 to invest and you put it all into Twitter at the IPO, your investment was worth about $164,000 at the end of 2013 - a gain of $64,000 in about 2 months! But what if you had diversified and put only $20,000 in Twitter and you invested $80,000 in other stocks? At the end of 2013, your Twitter stock was worth about $33,000 and so you only gained about $13,000 on Twitter, as opposed to $64,000 if you invested all your money in Twitter.
