Both the Dow and S&P 500 set fresh all-time highs as of Monday’s closing bell, ramping up in the final minutes of the regular trading day. Most of the session, positive sentiment had been rather tepid overall, but the race northward took the Dow up 173 points, +0.53%, the S&P 500 +0.64%, the Nasdaq +1.05% to lead all major indexes, and the small-cap Russell 2000 breaking into the green late in the day, +0.31%.As stimulus checks hit bank accounts across the nation and more Americans get their Covid-19 vaccine shots, pent-up demand in Travel & Leisure saw some big gains in select stocks today.

Shares of American Airlines AAL were up 7% on the day (+75% from a year ago) while United Airlines rose 8%. And Blackstone Group BX, along with Starwood, has paid $6 billion in all cash to purchase Extended Stay STAY, which gained 13.5% on the day.It wasn’t all stupendous news pointing to the Great American Reopening, however; as we mentioned, market indexes had been a tad lackluster for most of the trading day, only storming higher into the close. Eli Lilly LLY dropped 9% on a less-than-stellar note about its Alzheimer’s Disease drug testing, falling an additional 100 basis points ahead of the closing bell. The drug maker is still up 14% year to date, with its Covid antibody treatment showing good strides in keeping coronavirus sufferers out of the hospital.Tuesday morning we will see new economic data on Retail Sales, Import Prices and Industrial Production/Capacity Utilization, further articulating how price strength and productivity are manifesting in both Goods and Services industries over the past month.
