most of my stocks go up after I sell and go down after I buy.
That's the perfect argument for buying a company you believe in, and then relax, check the pps every few days, and wait for good clinical data. I've been buying PSTI for years (never sold any), some over current price, some under. My current average puts me in a very reasonable place with a very substantial holding. They say timing the market usually doesn't work out.
Like many investors your describe yourself as an impulse buyer and seller. Hardly ever works.
Follow the trends and try to avoid the emotion. Accumulate a little at a time. Unless the Trend convincingly turns down, just Hold and Relax. If you believe in the product and believe in the mgmt to steer the company in a positive direction, stay with it until proven wrong and use the T/A as a helpful tool.
