It is hard to find anything but good news in the current weekly insider-sentiment data from Vickers Stock Research. Volatility remains the order of the day in the stock market -- but for three consecutive weeks, the data from Vickers has suggested a bottom may be near, or already in. Let's jump right to the numbers. Vickers' NYSE One-Week Sell/Buy Ratio is 1.30 this week, this on a scale where anything below 2.00 is bullish. The ratio has been bullish for the past three weeks. Moving to the Nasdaq, the one-week ratio is 2.40. That is still neutral but closing in on bullish, and the ratio has been strong enough of late to engender nine consecutive weeks of improvement in the broader Nasdaq Eight-Week Sell/Buy Ratio. That reading has improved to 3.28 (neutral) from 5.20 back on March 10. All of the above has Vickers' Total (all exchanges) One-Week Sell/Buy Ratio at a bullish 1.76 and the Total Eight-Week Sell/Buy Ratio close to bullish at 2.63 after nine weeks of improvement. On a sector basis, insider buying exceeded selling in Financials last week, with shares valued at $4.5 million bought versus $3.9 million sold. Buying also outpaced selling in Energy, although volume was light with less than $100,000 shares bought during the period. Selling was the greatest in Consumer Discretionary over the last week, with shares valued at $21 million sold versus just $2 million bought. Selling was also notable in Industrials, Consumer Staples, and Healthcare. This week, analysts at Vickers highlighted insider transactions of interest at HEICO Corp. (NYSE: HEI) and Elevance Health Inc. (NYSE: ELV).

Despite bursts of outperformance, small- and mid-cap stocks (SMID) have underperformed large-caps year to date -- as they have over the past five years. But they may be in a better position to generate market-beating returns going forward. For one thing, SMID companies tend to focus on domestic markets, so their businesses could be less disrupted by the trade and tariff debate, or fallout from unrest in the Middle East, the Russian invasion of Ukraine, issues in China, or other geopolitical developments. As well, the prices of SMID stocks generally are lower than the prices of large-caps. Finally, there are long stretches in the record books when SMID stocks have outperformed large-caps. SMID stocks can be risky, but despite those risks, diversified investors look to have exposure to small- and mid-caps based on the long-term performance record. We estimate that 20% of the U.S. stock market's capitalization is comprised of SMID stocks.
