Personal Finance and Investing

I only buy/sell once a month. If the price goes up 15% within the first month after my initial purchase, I'll usually sell. Each consecutive month after that I'll add 7%, so if I'm up 22% in 2 months, 29% in 3 months, 36% in 4 months etc. then I'll sell. So, I could be holding it short-term or long term on this basis. And obviously if it takes so long that my calculated sell price has gone above a reasonable amount, I'll just sell when the time seems right - probably if it's at least 70% of the most recent historical high. So, 70% of 15.00 = 10.50.
