From the government taking stakes in Intel, Lithium Americas, and MP Materials, to sweeping political changes reshaping the economy, Stansberry argues a rare 'New 1776 Moment' is already underway. One Nobel Prize winner calls it a dividing line for all of society. His presentation covers the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.Watch Porter Stansberry's full briefing and learn how to prepare now 8/31/202422,230,000 shares $47.35 million +2.0%6.2%6.8 $2.13 8/15/202421,800,000 shares $39.24 million +12.3%6.1%6.5 $1.80 7/31/202419,410,000 shares $43.48 million -0.2%5.4%5.9 $2.24 7/15/202419,450,000 shares $41.04 million +55.6%5.4%6.2 $2.11 6/30/202412,500,000 shares $22.13 million -6.2%3.4%3.9 $1.77 6/15/202413,326,800 shares $28.65 million +0.4%3.7%4.9 $2.15 5/31/202413,270,000 shares $32.91 million +9.8%3.5%5.3 $2.48 5/15/202412,090,000 shares $30.59 million +5.9%3.3%4.8 $2.53 4/30/202411,420,000 shares $28.32 million +1.2%3.1%5 $2.48 4/15/202411,280,000 shares $31.25 million +10.3%3.1%5.5 $2.77 3/31/202410,230,000 shares $27.72 million +10.5%2.7%4.7 $2.71 3/15/20249,260,000 shares $24.26 million +16.9%3.3%5 $2.62 2/29/20247,920,000 shares $17.82 million -1.7%2.8%4.8 $2.25 2/15/20248,060,000 shares $20.15 million +10.4%2.9%5.8 $2.50 1/31/20247,300,000 shares $16.57 million -4.8%2.6%5.7 $2.27 1/15/20247,670,000 shares $16.49 million +33.2%2.7%6.6 $2.15 12/31/20235,760,000 shares $12.73 million +11.2%2.0%5.9 $2.21 12/15/20235,180,000 shares $10.31 million +26.0%6.6%6.7 $1.99 11/30/20234,110,000 shares $10.60 million +13.9%5.1%6.3 $2.58 11/15/20233,610,000 shares $7.94 million +6.5%4.7%5.7 $2.20 10/31/20233,390,000 shares $6.75 million -18.7%4.4%5.8 $1.99 10/15/20234,170,000 shares $6.63 million +18.5%5.4%8 $1.59 9/30/20233,520,000 shares $10.21 million +28.5%4.6%9.1 $2.90 9/15/20232,740,000 shares $7.70 million +7.5%3.6%10.7 $2.81 8/31/20232,550,000 shares $7.65 million -2.7%3.3%11.1 $3.00 8/15/20232,620,000 shares $7.52 million +4.8%3.4%10 $2.87 7/31/20232,500,000 shares $6.13 million -4.6%3.3%9.1 $2.45 7/15/20232,620,000 shares $6.16 million -1.9%3.4%9 $2.35 6/30/20232,670,000 shares $5.15 million -4.3%3.5%9.3 $1.93 6/15/20232,790,000 shares $6.17 million +0.4%3.7%9.3 $2.21 5/31/20232,780,000 shares $6.53 million -12.0%3.7%9.1 $2.35 5/15/20233,160,000 shares $6.00 million -2.8%4.2%11.5 $1.90 4/30/20233,250,000 shares $5.53 million +2.5%4.3%14.2 $1.70 4/15/20233,170,000 shares $5.71 million +18.7%4.1%13.9 $1.80 3/31/20232,670,000 shares $5.21 million +2.7%3.5%10.6 $1.95 3/15/20232,600,000 shares $5.36 million -15.0%3.4%10.6 $2.06 2/28/20233,060,000 shares $5.57 million +12.9%4.0%12.3 $1.82 2/15/20232,710,000 shares $5.69 million -6.9%3.5%11.1 $2.10 1/31/20232,910,000 shares $5.82 million -2.0%3.8%11.4 $2.00 1/15/20232,970,000 shares $5.94 million -8.9%3.8%11.4 $2.00 12/30/20223,260,000 shares $3.81 million -3.3%4.2%13.4 $1.17 12/15/20223,370,000 shares $4.58 million +2.7%4.4%14 $1.36 11/30/20223,280,000 shares $4.56 million -4.9%4.2%12.2 $1.39 11/15/20223,450,000 shares $5.24 million +0.3%4.5%11.2 $1.52 10/31/20223,440,000 shares $4.06 million -5.0%4.5%9.6 $1.18 10/15/20223,620,000 shares $3.73 million +0.3%4.7%8.4 $1.03 9/30/20223,610,000 shares $3.97 million -5.5%4.7%7.7 $1.10 9/15/20223,820,000 shares $5.04 million +11.7%5.0%5 $1.32 8/31/20223,420,000 shares $4.82 million -14.3%4.5%4.2 $1.41 8/15/20223,990,000 shares $8.22 million -18.1%5.2%3.8 $2.06Musk's acquisition pattern points to ONE stock (Ad)Musk needed solar - he acquired SolarCity.

The difference between the sell price and the buy price is the trader's profit. How does a short squeeze work against Standard BioTools?

Understanding short interest metrics can help you assess how traders are positioning around a stock like LAB:Shares Sold Short: The total number of shares that have been sold by short sellers but have not yet been covered or closed out. A high number may indicate bearish sentiment.Short Float: The percentage of a company’s publicly available shares (or "float") that are sold short. A higher short float suggests a greater portion of the stock is being bet against.Days to Cover (Short Interest Ratio): This estimates how many days it would take short sellers to cover their positions, based on average daily trading volume. Higher values can signal potential for a short squeeze if buying pressure increases.These metrics are often used by traders to gauge sentiment, volatility risk, and the potential for price movements based on short covering activity.
