long term trade

so looking over financials for GM they have a 9.1 Billion in open cash flow for operations. sales came in bigger than last year so i do expect there to be a small drop im going to do a long position at around $37 to $40 and then exit at around $50 per share so i did use the fib retracement to show where i think itll go short term but over all i think it will go long
