Nish Vartanian's addition to the Koppers Board is anticipated to have an immediate positive effect due to his four decades of success. His insight will enhance the Board's perspective and strength in holding Koppers leadership accountable for value creation.

Insider selling at Koppers Holdings, particularly below current price, is a negative sign. The absence of purchases in the last quarter and more selling than buying among insiders suggest caution before investing, despite the company's profitability and growth.

Koppers Holdings' share price may not fully reflect its future profit outlook, making it possibly a buying opportunity. Financial health and management track record are important considerations before investing.

Koppers Holdings' low P/E ratio is due to predicted growth being less than the market, possibly causing shareholder anxiety. The share price is unlikely to see a significant short-term increase.

Despite Koppers Holdings' strong performance, market sentiment is cautious given its low P/E ratio of 10.43. The company's EPS growth overtaking share price could indicate market under-appreciation.
