Apache Corporation

On April 23, 2019, pre-market, the Company announced that it had begun a "[t]emporary" deferral of natural gas production at its Alpine High oil-and-gas resource play in the Permian Basin. 

On this news, Apache's stock price fell $4.03, or nearly 11%, over the next four trading days, to close at $33.06 per share on April 26, 2019, thereby injuring investors.

On October 25, 2019, Apache's Senior Vice President of Worldwide Exploration, Steven Keenan, abruptly resigned from the Company. 

On this news, Apache's stock price fell $1.16, or 5%, to close at $22.07 per share on October 25, 2019, thereby injuring investors. 

Then, on February 26, 2020, post-market, the Company announced that it was completely de-valuing Alpine High after taking a $3 billion write-down on the project.  Two weeks later, on March 12, 2020, Apache announced that it had slashed its quarterly dividend by 90% (from $0.25 per share to just $0.025 per share) and was significantly reducing planned capital expenditures for the rest of 2020. 

On this news, Apache's stock price fell $0.49, or approximately 6%, to close at $7.76 per share on March 12, 2020, thereby injuring investors.

Finally, on March 16, 2020, Seeking Alpha published an article pre-market noting that Apache was particularly challenged among its peers, as the Company carried "the highest debt-to-equity ratio among large-cap independent [exploration and production companies],"  that "[t]he company doesn't have a strong balance sheet" and that its "financial health isn't great." 

On this news and other investment research downgrades, Apache's stock price fell $3.61, or approximately 45%, over two trading days, to close at $4.46 per share on March 17, 2020, thereby injuring investors further.
