Legendary investor and Berkshire Hathaway CEO/chairman Warren Buffett sees "substantial inflation" on the horizon, boosting the case for assets like the Vanguard Short-Term Inflation-Protected Securities Index Fund ETF Shares (VTIP). An ETF like VTIP can help investors hedge in this manner without having to purchase individual hedging components. VTIP seeks to track the performance of the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) 0-5 Year Index.
