this goes against the grain of common investing principles, but i invest with more peace of mind on two sometimes three stocks than i ever would with ten or twenty. how much research and time would i have to spend getting to intimently know each and everyone of those companies? 8 to 10x more time than i do now with the two or three i currently own. and as far as gambling goes concerning "betting the farm" on just a couple of stocks, think of it like this:
if you could go into a casino and step up to the roullette wheel, how could you almost gaurantee what number or color you pick will be the one that comes up? if you only pick a number, your odds are fewer but the payoff better (risk). if you pick a color, you have almost a 50% chance of winning, but with less payout (doubling is not bad tho). picking a stock is very similar, the more homework you do and the better the financial stability and near & long term growth looks, the better the chances the stock will go up. but back to the roullette wheel. what if you went up to place a bet, but now instead of half the numbers being red or black, say 90% of the wheel is black. would you feel much safer betting on black now? investing is like that. for every bit of research you do that turns up positive on that one stock, you have just increased the number of black spots on the wheel and your odds of return vs. loss are turning in your favor. picking a stock due to past performance and not realistically evaluating it's future performance is like betting on red when it has come up the last 5 times in a row. way too risky. what if you buy a stock because magillicuti or anybody said so? it's like putting your money on green 00. the odds are against you because you know nothing about the company, what they do, and how management responds to it's business environment. and as far as diversity goes, that's like the guy putting small bets around the table. he thinks he's being sensible and safe, but in the end he just lasted longer at the table then the fool who bet his wad on green 0 and lost. the name of the game is to stay ahead of the house (the market). i strongly believe with the necessary research, less diversification will win out over betting on the entire market every time. it's not for everyone but i've made over 50% in the past year with this strategy and handed the market it's ass, instead of vice versa
