This is not like pure science where you go, "Aha" and you've got the answer. By the time you've got "Aha," Chrysler's already quadrupled or Boeing's quadrupled. You have to take a little bit of risk. - Peter Lynch
Tips & Strategies - General
Keep most of your money "in the market" as much as possible. Money in the bank doesn't earn anything!
Know exactly what you own - the stock and how many shares and how much they are worth - at ALL times!
Know how much cash you have on hand - and which stock you'll sell to raise cash if you need it.
Watch for news and trading of stocks - both affect price.
Avoid investing in more stocks than you can easily keep track of.
Remember the COMMISSION! Once trading begins, you must pay a commission on every transaction. This means if you have $100,000, you cannot buy 2,000 shares of a $50 stock.
Don't panic the first time one of your stock drops, but ...
An underperforming stock not only costs you money, but time - remember there are only so many turns. Each minute waiting for a stock to turn around is one less minute you could be investing elsewhere.
Have an exit strategy - how much are you willing to lose on a stock before selling it? At what point will you sell a rising stock to bank your profits?
Get your rest the night before and don't skip breakfast - you'll need your energy!
