The viral picture is from 2017, and the message was run on the Thomson Reuters building in London, not on the New York Stock Exchange.
We conducted a reverse image search on the viral photo and found that the same image was shared by a Twitter user on March 12, 2017, with the statement, "This news is getting highlighted in canary wharf, the banking hub of London. Zoom it."
We also discovered that Amit Malviya, the BJP's IT cell in-charge, posted the same image on March 12, 2017, with the caption, "News of BJP's big win under Prime Minister Modi splashed in Canary Warf, prominent business district of London. Zoom it."
When searching the text of the scroll, "Modi wins landslide election victory in India's biggest state," a Reuters news report came up. The photo and accompanying article were published on March 11, 2017. Furthermore, on March 13, 2017, TV5 News broadcasted a news report about the BJP's victory in Uttar Pradesh, which was highlighted in London. The text "Modi wins overwhelming election victory in India's largest state" can be seen flashing on the building in the video.
India Today also refuted the claim, concluding that the viral image following the BJP's victory in the Uttar Pradesh assembly elections was outdated. The picture does not depict the New York Stock Exchange, as claimed.
Based on the available evidence, we mark this claim as false, as the image circulated is not from New York Stock Exchange, but instead the Reuters building in London.
