周二下午美国股市延续涨势，投资者密切关注美中之间的贸易谈判，同时等待周三上午公布的5月消费者价格指数。
道琼斯工业平均指数涨幅0.3%，标准普尔500指数上涨0.4%，纳斯达克综合指数上涨0.3%。
Liquidnet美洲市场结构主管杰夫·奥康纳表示：“市场似乎正在——至少是暂时——将注意力从新闻驱动的关税风险，转向真正重要的宏观经济数据。”
“由于明天将公布消费者价格指数，周四将公布生产者价格指数，投资者会关注这些数据是否会首次反映贸易政策有无传导至通胀”。
奥康纳还表示，标普500接近历史高点，如果经济数据出现大幅超出预期的情况，可能会“在很大程度上重新引发市场波动”，因为4月抛售后的迅速反弹“几乎没有为坏消息留下缓冲空间”。
他还说：“尽管表现尚可，但市场的交易环境仍然不健康。”（市场观察）

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
