Our 12–18 Month Outlook
Quality companies held over a multi-year horizon benefit from compounding fundamentals and the patience to ride through short-term volatility. Sandisk Corporation remains in our covered universe with a average-quality assessment. We update research when material data changes — earnings revisions, management shifts, or regime changes in valuation — not on every price fluctuation.
Long-term accumulation of quality businesses at fair or better prices is the core of the Patient Accumulator approach. Research updates like this one inform whether to add, hold, or wait for a better zone — not whether to react to short-term price moves.
