Three types of Investors in this volatile market

Few weeks ago, I came across an interesting article in The Business Times Weekend, which using a poker analogy to summaries the groups of investors perform the best and worst in these crises. Here are the extract of the article:

• Strong Hands
  They are not only emotionally strong enough to avoid selling into panic, but they are also have deep-enough pockets to avoid doing so for financial reasons. In fact, they are those who can actually profit by buying at cheap prices near the market bottom.
  
  
• Weak Hands
  They are those never harboured any illusions about being able to hold on. They "fold immediately and therefore suffer limited losses."Momentum investors, for example, fall into this category, because they constantly shift their portfolios away from securities that have lost the most money. Sometimes, they can turn up getting profit during this severe crisis because they may have shifted their portfolio to profit from the crisis.
  
  
• Strongest Weak Hands
  These investors are those that fall in between the above two groups, and usually end up losing the most money. These investors initially think they have a strong hand, and hold on for a while as their losses become more severe. Eventually, they discover that they aren't as strong as they initially thought - emotionally, financially or both. They are then forced to sell at or near the bottom.
