How long will the joyride continue? Lionsgate’s stock closed today +1.6% to $16.86, exceeding the previous record of $16.68 that it reached on November 9. While that’s the company’s best closing price, it’s still shy of the intra-day high of $17.02 that it hit on November 1. But execs at the independent studio have no reason to complain. Investors remain dazzled by Lionsgate’s string of successes this year including The Twilight Saga: Breaking Dawn Part 2, which has generated $227M at domestic box offices in its first two weeks. Lionsgate and Summit, acquired early this year, account for about 12.2% of the domestic box office so far this year, up from 5.8% for the two in the same period in 2011. And the company’s shares have appreciated nearly 111% in 2012.
