Foolish take
Northside Capital Management sold roughly one-fifth of its Vistra stake in the last quarter. However, I don't believe investors should view this negatively in regard to the stock.
First, Vistra shares were up 84% in the last six months alone. Northside opened its position in Vistra between April and June, so it may just be rebalancing or taking some quick profits from this rapid ascension.
Second, despite selling off this portion of its Vistra stake, the firm's portfolio allocation to the stock only dipped from 2.6% to 2.5%. Said another way, due to Vistra's rapidly rising price, the stock maintained its allocation despite the sale.
From a longer-term, Foolish perspective, Northside's decision to keep its remaining shares of Vistra makes a lot of sense. Vistra's management believes that the U.S. energy supply will have to grow five times faster than it did in the previous two decades as numerous megatrends fuel a boom in the need for energy.
Home to a rapidly growing and well-diversified portfolio of energy generation from gas, coal, nuclear, and renewable sources, Vistra looks like an excellent stock and top-tier capital allocator, now trading at a somewhat lofty valuation.
