A famous historian whose books have sold over 45 million copies in 65 languages is warning of a structural shift so large it has only one historical parallel - 1776.

Stansberry outlines the stocks to buy, the stocks to sell, and three money moves to position yourself on the right side of this shift.Read Porter Stansberry's full breakdown and protect your wealth nowNEONeoGenomics8/4/2025Set Price Target$5.45$11.00Overweight$0.0000.00% ROIWGSGeneDx8/4/2025Set Price Target$105.18$120.00Overweight$0.0000.00% ROIFLGTFulgent Genetics8/4/2025Set Price Target$18.18$21.00Neutral$0.0000.00% ROIWGSGeneDx7/9/2025Initiated Coverage$85.22$110.00Overweight$0.0000.00% ROITEMTempus AI5/15/2025Boost Price Target$63.76$70.00Neutral$00.0000.00% ROIPACBPacific Biosciences of California5/15/2025Lower Price Target$1.06$1.25Neutral$0.0000.00% ROINTRANatera5/15/2025Boost Price Target$149.42$210.00Overweight$000.0000.00% ROIILMNIllumina5/15/2025Lower Price Target$80.65$185.00Overweight$000.0000.00% ROIZTSZoetis5/12/2025Boost Price Target$162.37$210.00Overweight$00.0000.00% ROINEONeoGenomics5/6/2025Set Price Target$7.84$12.00Overweight$0.0000.00% ROILHLabcorp5/6/2025Reiterated Rating$245.96$280.00Neutral$000.0000.00% ROIGHGuardant Health5/6/2025Reiterated Rating$43.68$60.00Overweight$00.0000.00% ROIFLGTFulgent Genetics5/6/2025Reiterated Rating$18.96$23.00Neutral$00.0000.00% ROIADPTAdaptive Biotechnologies5/6/2025Reiterated Rating$10.03$13.00Overweight$00.0000.00% ROIDGXQuest Diagnostics4/28/2025Boost Price Target$175.47$200.00Neutral$000.0000.00% ROINEOGNeogen4/22/2025Lower Price Target$4.82$5.00Neutral$0.0000.00% ROINEOGNeogen4/14/2025Lower Price Target$5.58$6.50Neutral$0.0000.00% ROIAKYAAkoya Biosciences4/14/2025Lower Price Target$1.23$1.65Neutral$0.0000.00% ROIELANElanco Animal Health3/6/2025Lower Price Target$10.77$12.00Neutral$00.0000.00% ROICTKBCytek Biosciences3/4/2025Lower Price Target$4.30$8.00Overweight$0.0000.00% ROITEMTempus AI3/4/2025Lower Price Target$50.13$55.00Neutral$00.0000.00% ROINTRANatera3/4/2025Boost Price Target$137.97$205.00Overweight$000.0000.00% ROIFLGTFulgent Genetics3/4/2025Lower Price Target$14.98$16.00Neutral$00.0000.00% ROIZTSZoetis2/27/2025Boost Price Target$164.99$205.00Overweight$000.0000.00% ROINEONeoGenomics2/26/2025Lower Price Target$10.64$18.00Overweight$0.0000.00% ROIGHGuardant Health2/26/2025Boost Price Target$43.13$50.00Overweight$00.0000.00% ROIEXASExact Sciences2/26/2025Lower Price Target$48.71$70.00Overweight$000.0000.00% ROIPACBPacific Biosciences of California2/20/2025Reiterated Rating$1.63$2.00Neutral$0.0000.00% ROIADPTAdaptive Biotechnologies2/20/2025Reiterated Rating$8.48$11.00Overweight$00.0000.00% ROIILMNIllumina2/10/2025Boost Price Target$103.65$190.00Overweight$000.0000.00% ROIZTSZoetis2/10/2025Lower Price Target$171.12$200.00Overweight$000.0000.00% ROIIDXXIDEXX Laboratories2/10/2025Boost Price Target$463.58$510.00Neutral$000.0000.00% ROIDGXQuest Diagnostics2/3/2025Reiterated Rating$161.06$180.00Neutral$000.0000.00% ROINEOGNeogen1/21/2025Reiterated Rating$11.78$13.00Neutral$0.0000.00% ROI Stock Forecasts and Research Tools Today's Analyst Ratings U.S. Ratings U.K. Ratings Canadian Ratings All Upgrades All Downgrades All Initiations All Price Target Changes Top-Rated Stocks Top Rated Stocks Top-Rated Dividend Stocks Top-Rated Small-Cap Stocks Top-Rated Tech Stocks Most-Upgraded Stocks Most-Downgraded Stocks Lowest-Rated Stocks More Ratings Tools Stock Ratings by Issuer Top-Rated Analysts Top-Rated Brokerages Stock Ratings Screener Free Ratings Newsletter Price Forecasts for Popular Stocks Alphabet (Google) Stock ForecastAmazon Stock ForecastApple Stock ForecastMeta (Facebook) Stock ForecastMicrosoft Stock ForecastNetflix Stock ForecastNvidia Stock ForecastTesla Stock Forecast Top Stock Recommendations by BrokerageWall Street ZenUBS GroupCitigroupBarclaysWells Fargo & CompanyMorgan StanleyRoyal Bank Of CanadaJPMorgan Chase & Co.Jefferies Financial GroupThe Goldman Sachs GroupTD CowenTruist FinancialPiper SandlerStifel NicolausRaymond James Financial Get 30 Days of MarketBeat All Access for Free Sign up for MarketBeat All Access to gain access to MarketBeat's full suite of research tools.
