AMC Entertainment stock jumps toward 8th straight gain

Shares of AMC Entertainment Holdings Inc. AMC, -0.50% shot up 7.8% in premarket trading Tuesday, putting them on track for an eighth straight gain, which would be the longest win streak in nearly three years. The movie theater operator's stock has rocketed 68.6% over the past seven days, which would be the best seven-day performance since the height of the trading frenzy surrounding so-called meme stocks in early February. In comparison, shares of fellow movie theater operator Cinemark Holdings Inc. CNK, +0.05% have gained 7.7% over the past seven sessions, but has lost ground on four of those days. The stock is also set to open at the highest price seen during regular trading sessions since Feb. 1. AMC shares have recently received a boost from renewed interest by retail investors, as reported by MarketWatch's Thornton McEnery. The last time the stock rose for eight straight days was the eight-day streak that ended Aug. 23, 2018; during that eight-day streak, the stock rose just 10.0%. AMC shares have rocketed 558.0% year to date through Monday, while the S&P 500 SPX, -0.04% has tacked on 10.8%.
