Recommendation: Sell 1000 Shares @ Market (Hold remaining 1000 shares)

Projection & Valuation Hold 1000 shares Sell 1000 shares at market price The industry is growing. Company’s business model is promising. They have achieved positive earnings since 2010. Based on DCF Sce2 (with tax benefits), there is still room for the stock price to increase. CON Zix doesn’t pay any dividend. Company can easily use deferred tax assets to manipulate net income The actual value of deferred tax assets remains questionable.
