The stock market stalled last week after an impressive run that saw the S&P 500 bolt from 4982 in late April to 5659 at the close on Friday. Insider sentiment moved mostly in lock-step with that surge, though the insider-sentiment data from Vickers Stock Research turned bullish during the week of April 7, ahead of the market's bullish run. Last week, insider-sentiment again mirrored the broader market by 'stalling' but not fading. On a scale where sentiment is bullish under 2.00 and neutral from 2.00 to 6.00, the NYSE Eight-Week Sell/Buy Ratio from Vickers is now 2.01 versus 1.83 last week, representing a slight fallback. For the Nasdaq, there was some improvement, with the Nasdaq Eight-Week Sell/Buy Ratio at 2.87 this week versus 2.98 last week. Putting all the data together, Vickers' Total (all exchanges) Eight-Week Sell/Buy Ratio is currently 2.39, essentially unchanged from 2.34 last week. So insider sentiment stalled, but in a pretty positive place. Insider selling outpaced insider buying across all sectors over the last week, but insider buying in the Consumer Discretionary sector lagged selling by a factor of just 2.0-times. Selling was the greatest in Consumer Staples over the last week, with shares valued at $111 million sold versus just $2 million bought. Selling was also notable in Financials, with shares valued at $99 million sold versus just $5 million bought, as well as Healthcare, where insiders sold shares valued at $97 million versus $7 million bought. This week, analysts at Vickers highlighted insider transactions of interest at CrowdStrike Holdings Inc. (NGS: CRWD) and GoDaddy Inc. (NYSE: GDDY).
