Based on IBM chart, the stock should have done its wave WXY correction.
Prices in wave Y phase are consolidated within the expanding diagonal (A)(B)(C)(D)(E) pattern though there is spike of price earlier with false breakout. But prices are later further corrected to about 61.8% FIBO level.
Further breakout from the diagonal pattern will trigger buy signal and likely further confirms of reversal uptrend movement.
Happy trading!
