What this transaction means for investors

Director Spinelli's purchase is certainly worth noting, in my opinion. While it may not be a massive purchase, it was made with Spinelli's own cash and signals that they think the stock is a buy following a couple of quarters of less-than-perfect earnings. That said, investors should note that Spinelli is a director, as opposed to an insider who sees the day-to-day operations of the company, so they likely don't have as clear a view as the CEO, for example.

When considering the purchase alongside PLNT stock's declining share price, it makes quite a bit of sense as a buy-the-dip opportunity. Planet Fitness currently trades at merely 15.6 times free cash flow, its lowest mark in nearly a decade. The main reason for this cheap valuation is that the company's same-club sales continue to slide, falling to only 1.7% in its latest quarter.

This is important for investors, as Planet Fitness already has 2,930 clubs, so there may not be much room for expansion going forward. Management believes they can reach 5,000 locations, but even if that happens over time, the company still needs some same-club sales growth for the stock to succeed, and customers have balked at recent price hikes. While PLNT stock's valuation is certainly appealing -- and I can see why Spinelli is buying -- I'm not in a rush to buy shares until I see the company display better pricing power.
