If there is a ten thousand dollar investment and a stock goes from $65 per share to say $70 per share, how much was approximately made?

Let's see... You make $5/share in capital gain, and the number of shares you originally bought was 10,000/65, or 153. 85 shares, so you made approximately $769.23. That's before taxes - take 20% or so for capital gains, plus whatever your state income tax rate is, and perhaps you clear $600 or so after taxes.

So, why is the title of this post "60000 in 90 days"? Perhaps you're counting pennies?

I think 1,00 but I don't know for sure

Like I said in the PM, what is the price you bought the shares at?

If it indeed was at 65, then ebaines has correctly answered your question.

153 shares with an increase of $5.00 per share, you would make roughly $769.23. I would sell! Now! ebaines is correct. Divide 10,000 by 65 and you get 153.8. shares. X $5.00 = $769.23.
$60.000 in 90 days? You must be a gopher for Goldman Sachs.
