Shares of Windstream Holdings (NASDAQ: WIN) plunged 43% in the first half of 2018, according to data from S&P Global Market Intelligence. Weak business results played a major part in this decline, and the asset-less telecom's early summer also saw several desperate-looking financing moves.February's breakeven fourth-quarter earnings and 14% year-over-year revenue growth actually wasn't a terrible report, triggering a quick 19% jump the next day, but those gains faded to a 13% drop before the closing bell, and share prices largely continued their usual slide anyhow.
