Frequently Asked Questions

What does Gardner Lewis Asset Management L P invest in?
Gardner Lewis Asset Management employs a Growth at a Reasonable Price (GARP) investment philosophy that seeks companies demonstrating sustainable competitive advantages, consistent earnings growth, and strong management quality while avoiding valuation extremes that characterize momentum-driven growth investing. The firm's **13F Portfolio Composition** reveals concentrated exposure to established quality growth companies across multiple sectors, emphasizing businesses with durable franchise value, pricing power, and the ability to compound earnings through economic cycles. This approach differs fundamentally from both deep value investing focused on distressed or cyclical turnarounds and aggressive growth strategies willing to pay premium valuations for maximum revenue expansion regardless of profitability or valuation discipline. The investment philosophy at Gardner Lewis reflects understanding that superior long-term wealth accumulation emerges from owning exceptional businesses purchased at reasonable valuations and held through market volatility rather than from frequent trading or market timing attempts. Portfolio construction decisions observable through decades of quarterly 13F filings demonstrate remarkable consistency in identifying quality characteristics: strong returns on invested capital, sustainable competitive moats, excellent management teams, and business models capable of generating cash flows across varying economic environments. The firm's **Sector Allocation History** reveals diversified exposure across technology, healthcare, consumer, financial, and industrial sectors, avoiding both extreme sector concentration and rigid sector allocation mandates, instead allowing bottom-up security selection to determine portfolio composition within broad diversification parameters. Gardner Lewis Asset Management's turnover characteristics reflect genuinely low-turnover, buy-and-hold orientation where portfolio positions are measured in years rather than quarters, with holdings maintained through temporary setbacks when underlying business quality and competitive position remain intact. This patient capital approach creates tax efficiency for taxable accounts, minimizes transaction costs, and allows compound interest to work over extended periods—advantages that accrue to long-term investors but require tolerance for short-term tracking error during periods when momentum strategies or speculative themes dominate market returns. For institutional allocators evaluating core equity managers, historical performance replication through backtesting of Gardner Lewis's disclosed 13F positions enables objective assessment of whether GARP methodology and low-turnover discipline have delivered competitive risk-adjusted outcomes across complete market cycles spanning multiple decades.
