Why Is Reddit Stock Surging on Friday?

Reddit Inc. (NYSE:RDDT) stock is rising Friday after S&P Dow Jones Indices announced the company will join the S&P 500 index.

The announcement came late Thursday. Nasdaq futures are up 0.20% while S&P 500 futures have gained 0.09%.

Reddit Set to Join Benchmark Index

S&P Dow Jones Indices said Reddit will replace AvalonBay Communities Inc. (NYSE:AVB) in the S&P 500, effective before the opening bell on Tuesday.

The index seat is opening because AvalonBay is merging with fellow S&P 500 member Equity Residential (NYSE:EQR) in a merger of equals. Shareholders of both companies approved the deal this week, with more than 99% of votes cast at each company’s special meeting in favor.

The transaction could close as soon as Monday. Under the deal terms, each AvalonBay stock converts into 2.793 units of Equity Residential stock.

Combined Company Retains Index Membership

Once the merger closes, the combined company will drop both existing names and take on the name Vivmark Residential.

It will trade on the NYSE under the ticker VMRK starting August 18, and will keep its place in the S&P 500 rather than exit the index.

Critical Price Levels To Watch For Reddit (RDDT)

From a trend perspective, RDDT is trading 5.2% above its 20-day SMA ($166.00) and 6.8% above its 100-day SMA ($163.45), but it’s still 2% below its 200-day SMA ($178.07), which keeps the longer-term trend line as the next big hurdle. It’s also essentially flat versus the 50-day SMA ($174.85), trading 0.2% below it—so this rally is happening right at a "decision zone" where breakouts can either stick or fade.

The bigger-picture moving-average structure is still a headwind: the 20-day SMA remains below the 50-day SMA (bearish), and the death cross (50-day below 200-day) that occurred in March signals the longer-term trend has been under pressure. That said, a strong push through the 200-day area would be a meaningful character change because it would put price back above the most-watched long-term average.

• Key Resistance: $186 — a nearby round-number zone where rebounds can stall, especially with the 200-day SMA ($178.07) still overhead.
• Key Support: $152.50 — a prior buyer-defense area that sits well below current price, making it a key "line in the sand" if the gap starts to unwind.

RDDT Price Action: Reddit shares were up 10.99% at $175.49 during premarket trading on Friday, according to Benzinga Pro data.
