SpaceX Shares Rise as Musk Says Wall Street Underestimates Growth

SPCX closed at $136.91 on August 21, 2026, up 2.17% from the prior close of $134.00.

Executive Summary

SPCX snapped a three-session slide on August 21, opening at $134.27, dipping to an intraday low of $131.22, then reversing to close near the session high at $136.91. The bounce followed a run of headlines around SpaceX's launch cadence and growth narrative: President Trump ordered federal agencies to raise the U.S. rocket launch pace to 1,000 per year by 2030, Elon Musk said SpaceX could reach 10,000 Starship launches annually by that same year, and Wall Street's projected 7-to-1 revenue growth edge over Nvidia (which Musk called too conservative) circulated through the trading day. A Falcon 9 mission carrying 29 Starlink satellites from Florida was also reported as underway.

Volume on the session was 71,333,534 shares, well below both the prior day's 119,878,075 and the trailing average of 118,425,365, so today's rebound came on lighter-than-normal participation. The close of $136.91 puts the stock back above both the $134.00 prior close and the $135.00 IPO offer price after briefly trading below both intraday.

Price Action

Metric	Value
Open	$134.27
High	$137.35
Low	$131.22
Close	$136.91
Change vs prior close	+2.17% ($134.00 → $136.91)
Volume	71,333,534
Intraday range	$6.13 ($131.22–$137.35)
Close vs IPO offer price ($135.00)	+1.41%

SPCX opened at $134.27, just above the prior close, then sold off to $131.22 in the early part of the session — briefly trading below both the prior close and the $135.00 IPO offer price. From there the stock reversed and climbed through the rest of the day, finishing at $136.91, near the top of its $6.13 intraday range. Volume of 71.3 million shares ran at roughly 60% of the 118.4-million trailing average and well under the prior session's 119.9 million shares, so the recovery was not accompanied by heavier-than-usual trading.

Takeaway: SPCX reversed an early breakdown below the IPO offer price to close up 2.17% on below-average volume, ending the session near its intraday high.

Technicals

SPCX has traded for roughly two months since its June 12, 2026 IPO, so the 50-day and 200-day moving averages remain unavailable — there is not yet enough price history to compute them, and the registry correctly withholds them rather than approximating off a shorter window. Shorter-window measures (RSI-14, SMA-5/10/20) are computable and shown below, but with a still-young, still-settling data set they should be read as directional context rather than a mature technical picture.

Trend

Following its June 12 IPO, SPCX peaked at a $201.80 close on June 16, then declined through most of July to a closing low of $108.37 on July 31. From there it rallied into mid-August, closing as high as $146.23 on August 17, before pulling back over four sessions to $134.00 on August 20. Today's close of $136.91 sits above the SMA-20 ($127.94) but below the SMA-5 ($140.03), SMA-10 ($139.96), and EMA-5 ($138.05) — consistent with a stock still working through a short-term pullback inside a medium-term recovery from the July lows.

Candle read

Today's candle has a body of $2.64, an upper wick of $0.44, and a lower wick of $3.05, against a total range of $6.13. The lower wick accounts for roughly half the day's range, while the upper wick is minimal. Close location of 0.93 means the close sat 93% of the way up the day's range. That combination — a long lower wick, short upper wick, and a close near the day's high — reads as a bullish reversal candle: price was pushed down to $131.22 intraday and then bought back up through the rest of the session.

Support levels

• $131.22 — today's intraday low, the level defended in the reversal.
• $134.00–$135.00 — the prior close ($134.00) and IPO offer price ($135.00), both briefly broken intraday before the close recovered above them.
• $127.94 — the SMA-20, the next level down if the recovery fails.

Resistance levels

• $137.35 — today's intraday high.
• $139.96–$140.03 — the SMA-10 and SMA-5 cluster.
• $146.23 — the August 17 closing high, the most recent swing high.

Momentum interpretation

Bull scenario: a move back above the SMA-5/EMA-5 zone ($138.05–$140.03) that also clears today's high of $137.35 would put the August 17 swing high of $146.23 back in play.

Bear scenario: a break back below today's low of $131.22 and the $134.00–$135.00 prior-close/IPO-offer-price zone would open the SMA-20 at $127.94 as the next reference point.

Neutral scenario: RSI-14 at 51.79 sits near the midpoint with no overbought or oversold reading, consistent with continued consolidation between roughly $131 and $140 absent a fresh catalyst.

Trading Takeaway

SPCX reversed an early break below its IPO offer price to close up 2.17% on lighter-than-average volume, finishing near the session high after defending $131.22. The close remains below the SMA-5/SMA-10 cluster near $140, so today's move reads as a bounce within a short-term pullback rather than a confirmed trend change. For the next session, the levels to watch are resistance at $137.35 (today's high) and the $139.96–$140.03 moving-average cluster above it, against support at $134.00–$135.00 (prior close / IPO offer price) and $131.22 (today's low) below.
