Corning Incorporated (NYSE:GLW) experienced a significant decline of nearly 7% in its stock price following reports of substantial insider selling. This downturn has prompted speculation about a potential rebound, as historical price levels indicate that previous resistance points can transform into support. Specifically, the $175 price level, which was a resistance in April, may attract remorseful sellers who regret their previous decisions to sell. When the stock price falls back to these levels, these sellers often place buy orders, creating a support base. This pattern was observed when Corning's stock previously dropped to $150, where a similar influx of buy orders led to a rally. If enough remorseful sellers act at the $175 level, it could catalyze another upward movement in the stock price. The interplay between anxious buyers and sellers could result in a bidding war, driving prices higher as buyers compete to secure shares before prices rise further.
